On September 27, 1912, Shanghai was shrouded in a cloud and mist, just a rain, the sky has not completely cleared, in the dock of Jiangnan Shipyard, a light and small steamboat, slowly sailed into the Huangpu River, and then began to trace along the Huangpu River, the destination is Nanjing, this is the simple name of the West 111 all-electric welding processing steamship, carried out the first long-distance voyage, can change the entire shipbuilding history, on behalf of more advanced shipbuilding production technology welding, on this day, Officially on the stage of history, the Northwest and China, through all aspects, retained this technology for up to 3 years, accumulated huge experience and technology, with this vision of various technologies, so that China's shipbuilding industry, from the end of the world, began to catch up with the pace of advancement, creating one glory after another.

The steamboat was launched slowly, without alarming anyone, because this dock is top secret, there is a company of regular troops around, and because of Yang Yuanzhao's attention, almost 500 meters around, no one will approach, and take advantage of the night, quietly launched, no one found that the short-distance sea trial has been carried out 3 times, the highest one reached 30 kilometers, this is after several improvements and corrections, the fourth sea trial, will exceed 300 kilometers, it can be regarded as the ability to try long-distance.

In the previous 3 sea trials, the table of the steamboat is extremely good, because the structure is smoother, the coal consumption of the same voyage is less than expected, plus the excellent steam engine in Baotou, even if no changes are made, the performance of this steamboat is also about 1,000 tons of steamboat, the best performance, once put on the market, it will cause a lot of chase.

Different from 10,000-ton ocean-going cargo ships, the competition of 1,000-ton is more intense, and it can be said unceremoniously that a little improvement in performance may cause huge fluctuations, although the profit margin is not high, but it is a winner-take-all, loser loses.

However, the simple sea trial made Wang Benchu see more improvement plans, some of which can be directly fine-tuned to the steamboat, and some of which must be modified in the design of the next level, based on the benefits of electric welding, far more than that.

Wang Benchu from this moment, devoted to study, and later became a master of electric welding shipbuilding, but also the result of coincidence and talent cooperation, now this without any string number of steamboats, quietly, integrated into the lower reaches of the Yangtze River cargo ships, is not at all inconspicuous, as the world's second longest river, the Yangtze River, not only there are 1,000-ton steamboats, but also a large number of other ships, and even in the summer of large water volumes, 10,000-ton cargo ships can even be traced back to Wuhan.

The test number jù is as a precious real information, which has been saved, but Yang Yuanzhao is busy with something else, in the middle and late stages of the construction of this ship, he has rarely come to Jiangnan Shipyard in person, his purpose is to adjust Jiangnan Shipyard, let him get on the right track, in fact, this only took a few days, it was completed, and after an appointment with Mu Mo for another month, he couldn't be idle, Yang Yuanzhao didn't have more things to deal with, and he couldn't do nothing, he naturally put his thoughts, It's in an all-in-one machine.

The biggest three advantages of the shipbuilding industry in the northwest in the future, on the one hand, electric welding, has now been gradually utilized, 300 tons of steamboats, is just a preliminary beginning, the next need to gradually explore, to get a system, with the help of Jiangnan Shipyard began to explore, the future when Qingdao Shipyard is completed, will turn to that place. Another advantage is power, which has built a large steam engine group and a steam turbine group in the northwest, with the help of an all-in-one machine and Yang Yuanzhao's forward-looking vision, which can make them more smooth development, and the last aspect is materials.

The previous ship deck, even if he strengthened, could only be regarded as a line beyond the ship deck of this era, in order to obtain a greater advantage, better materials were an inevitable choice, and this time, Yang Yuanzhao set his sights on special trace materials.

Tungsten and other important trace raw materials, China has a lot of reserves, and the application of it in later generations has been much weaker than the world's top level, but some new materials and new projects based on these materials have become the mainstream of the world's material development in the 21st century.

Yang Yuanzhao is not only a traverser, but also has such a golden finger as an all-in-one machine, in terms of materials, he has a natural advantage, which even the powers are incomparable, from knowing the material function of the all-in-one machine, Yang Yuanzhao even if he is busy, every day will choose a different combination, because considering the capacity of the Baotou processing plant, he did not choose rare earth elements, although this is China's largest reserves, Baiyun Obo iron ore, also accompanied by a large number of rare earth materials.

However, Yang Yuanzhao is very clear that in this era, the use of rare earths is a little too early, although some of the materials added by rare earths, the performance and difficulty of realization are not difficult, but the purification of rare earths, until later generations, is also a problem that is not easy to solve, in this era, it is almost impossible, and the other effect is not high, but it is a waste of rare earth resources.

From the countless kinds of material ratio, to find new materials, it is definitely not easy, every point of change, each annealing and forging method of different, will cause earth-shaking changes in materials, but most of them are waste, otherwise the material will not become a problem in many countries, the basic discipline based on materials, all are huge investment, slow results of the industry.

Fortunately, with the help of the all-in-one machine, Yang Yuanzhao has a natural advantage in the research materials, especially now, the material discipline in the northwest has always been the top priority, after providing the physical object and a full set of performance indicators, some cutting-edge scientists, began to find out some inevitable connection in countless different materials, this connection, feedback to Yang Yuanzhao here, and then use the all-in-one machine to continue to work in this direction, it has formed a variety of material systems in the northwest.

Most of the materials that exceed this era, or the performance is too amazing, Yang Yuanzhao did not take it out, and now there are just ten days, whether it is a steamboat or the modification of Jiangnan Shipyard, there is no need for him to worry about it, and he just has the time to soak in the sea of materials.

At present, several major items, such as tungsten, lithium, titanium, zirconium, hafnium, vanadium, niobium, tantalum, molybdenum, among these materials, some of them have been produced in later generations, and some are simply based on the all-in-one machine, and they are forced to open, but a few years of research have reached a bottleneck, each system, choose 1000 per day as the accumulation, this is Yang Yuanzhao's normalized practice, and now there is just a whole day, in the absence of other breakthroughs, Yang Yuanzhao naturally chose rare earths.

All kinds of rare earth substances are added to the metal to form alloys, which is a new material production method, is after the 80s of the 20th century, it is an emerging technology that has gradually developed, in a sense, polymers, high-performance materials, all related to rare earth elements, but in this era, rare earths are only some newly discovered elements, everyone is basically immersed in purification, and even how many elements are in rare earths may not be able to say, The concept of heavy and light rare earths has only just taken shape.

Yang Yuanzhao is from the later generations, for rare earth research is not much, but also know some special rare earth elements, for the importance of alloys, especially high-quality alloys, with the help of the all-in-one machine, in purification, the all-in-one machine can be completely purified, the added elements, are also injected into a variety of steel materials, the reputation of the king of material addition, it can be said that in rare earth and other materials, there is no doubt, which has formed a series of different alloys.

It seems that the potential of rare earth materials has not really been brought into play, and after quietly filing all the materials and formulas, Yang Yuanzhao began to examine one of the materials in detail.

This material, which was named Armor Steel No. 17 by Yang Yuanzhao, was scanned by the Guò all-in-one machine and obtained all the information, and it is an alloy material that is extremely suitable as armor steel.

Yang Yuanzhao originally did not plan to add the alloy of rare earth materials, the actual production, but this alloy, but it made it difficult for him to choose, referring to the German battleship, especially after the large 10,000-ton cruiser, among the all-in-one machine, there are several more formulas for the steel deck, and the performance is beyond the world's mainstream armor steel, this improvement has been quite obvious, for large warships, especially for warships of more than 20,000 tons, no ton has a relative effect, saving weight, It will give the performance of the battleship a big boost.

This was originally intended to be used as a secret material, and in the future, it was necessary to cooperate with Germany to a large extent, but in the future, the Northwest would obtain a considerable amount of ship information from Germany under the condition of paying a certain amount of funds, raw materials, power equipment, deck steel, and manufacturing capacity, so as to form the Northwest's own shipbuilding capacity.

However, this Yang Yuanzhao casually added heavy rare earth materials to the steel, mainly ordinary steel, adding some titanium, nickel, niobium and vanadium, but unexpectedly formed a new alloy, this alloy hardness, corrosion resistance, weight, are compared with the original deck steel has a huge advantage, is a natural marine armor steel, his hardness is equivalent to the current strongest armor steel more than double, toughness and other processing capabilities, is also quite outstanding.

The performance of the thing is too good, this has become a problem, Yang Yuanzhao is difficult to decide for a while, whether to produce it or not, as another fist product in the northwest, this is extremely difficult to decide, Yang Yuanzhao is very clear about the chance of this new material obtained, by chance to maybe in the next one or two years, it may not be possible to get such an excellent material through the random synthesis of the all-in-one machine, don't take it out, more or less unwillingly, take it out, the northwest can't get the maximum benefit, in case the formula leaks, I am afraid that the biggest benefit is the current naval power, the northwest, which has just hit the road.
